Korea’s Crypto Chaos: Fat Fingers, Flash Crashes, and Circuit Breakers!
Now, picture this: Bithumb, in a fit of generosity, decides to sprinkle a little Bitcoin fairy dust on its customers. But lo and behold, some poor sap behind the keyboard must’ve had a case of the Mondays, ’cause instead of sendin’ out $460 worth of Bitcoin, they unleashed a torrent worth billions. Talk about a promotional event gone sideways! The BOK folks say Bithumb’s systems were about as secure as a sieve, and their fraud detection was sleepin’ on the job. Result? A flash crash that made the Great Train Robbery look like a petty theft.
